I adore tinkering with my car and small engines, and this product has revolutionized my projects. From sealing a valve cover to achieving flawless results with zero leaks, the quick setting and strong hold blew me away. Using the caulking gun for even application is a dream compared to the hassle of small tubes. Highly recommend it!

I'm seriously blown away by the Permatex 25228 The Right Stuff 90 Minute Black Gasket Maker. It's like a magic potion for fixing things! The ease of use is off the charts - it's a total game-changer for any DIY project. The best part? It sets in just 90 minutes, so you can get back to business in no time. The 3 oz tube is more than enough for most jobs, making it super cost-effective. I've used it on multiple projects and it has never let me down. The only downside is that it's a bit messy to work with, but hey, that's the price you pay for such a fantastic product! I highly recommend it to anyone who loves fixing things around the house.
